使用未解析的標識符「單元格」

我在一個視圖控制器中創建了多個UITableViews，並且我使用下面的代碼來檢查它是哪個tableView。我一直在問題「在最後一行中使用未解析的標識符」單元格。我試過尋找這個，但是在Xcode 7中並沒有太多最新的東西。請原諒我缺乏術語以及的經驗，我剛開始起飛了，請隨時問我的，你可能遇到的任何問題，謝謝大家提前誰花時間閱讀這篇文章的時候！使用未解析的標識符「單元格」

@IBOutlet var tableView1: UITableView! 
@IBOutlet var tableView2: UITableView! 

// Mens games Variables 
var dates = ["7/23", "7/24","7/25","7/26","7/27","7/28","7/29"] 
var times = ["7:30","8:00","8:30","9:00","9:30","10:00","10:30"] 
var teamsOne = ["VU Reserves 1","VU Reserves 3","VU Reserves 5","VU Reserves 7","VU Reserves 9","VU Reserves 11","VU Reserves 13"] 
var teamsTwo = ["VU Reserves 2","VU Reserves 4","VU Reserves 6","VU Reserves 8","VU Reserves 10","VU Reserves 12","VU Reserves 14"]

這是因爲上次返回單元格沒有聲明。 – Chandan

我照你告訴我的那樣做了，但是我現在得到錯誤，說「常量」單元格在被初始化之前使用了「 –

我已經更新了答案請現在嘗試 – Chandan

只需用下面的代碼

取代的cellForRowAtIndexPath

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell { 
var cell:UITableViewCell? 

if (tableView == tableView1) { 

cell = self.tableView1.dequeueReusableCellWithIdentifier("cell1", forIndexPath: indexPath) as! gamesCustomCell 

cell.date.text = dates[indexPath.row] 
cell.time.text = times[indexPath.row] 
cell.teamOne.text = teamsOne[indexPath.row] 
cell.teamTwo.text = teamsTwo[indexPath.row] 
cell.field.text = fields[indexPath.row] 

} 
if (tableView == tableView2) { 

    cell = self.tableView2.dequeueReusableCellWithIdentifier("cell2", forIndexPath: indexPath) as! womensGamesCustomCell 

    cell.womensDate.text = womensDates[indexPath.row] 
    cell.womensTime.text = womensTimes[indexPath.row] 
    cell.womensTeamOne.text = womensTeamsOne[indexPath.row] 
    cell.womensTeamTwo.text = womensTeamsTwo[indexPath.row] 

} 

return cell! 
}

如果您在最後強制解包它，單元不需要ti是一個可選項。 – penatheboss

試試這個，它爲我工作

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell { 
    if (tableView == tableView1) { 
    let cell = self.tableView1.dequeueReusableCellWithIdentifier("cell1", forIndexPath: indexPath) as! gamesCustomCell 

    cell.date.text = dates[indexPath.row] 
    cell.time.text = times[indexPath.row] 
    cell.teamOne.text = teamsOne[indexPath.row] 
    cell.teamTwo.text = teamsTwo[indexPath.row] 
    cell.field.text = fields[indexPath.row] 

    return cell 

    } else if (tableView == tableView2) { 
    let cell = self.tableView2.dequeueReusableCellWithIdentifier("cell2", forIndexPath: indexPath) as! womensGamesCustomCell 

    cell.womensDate.text = womensDates[indexPath.row] 
    cell.womensTime.text = womensTimes[indexPath.row] 
    cell.womensTeamOne.text = womensTeamsOne[indexPath.row] 
    cell.womensTeamTwo.text = womensTeamsTwo[indexPath.row] 

    return cell 
    } 

    return UITableViewCell() 
}
